Abilities
For Gwendolyn’s abilities, here are the basics you should pick up as soon as you have enough points: Recovery Up, Charge Up, and Power Supply. These are all tier 2 and 3 abilities, so you can grab them pretty early in the game. These abilities will ensure that you’ll always have enough POW for skill usage, as well as keeping your health high should you be forced to eat your food in the middle of the battle.
For offensive abilities, Counter Guard and Shield Bash are particularly useful for people who enjoy blocking. These abilities allow you to increase your damage output right after blocking an attack. If you’re not a fan of blocking attacks, be sure to go for Backstab and Aerial Force. These are abilities that increase your damage whenever you hit enemies from behind, or in the air.
If you’ve got enough ability points left before the end of Gwendolyn’s campaign, feel free to go for Skull Bash too. This gives you a chance of inflicting the Dizzy effect onto opponents right after a successful block.
